"STY (Stirling Technology)"
(Holy cow. Is that acronym for STirling technologY or Stirling TechnologY?)
I'm really surprised that more effort hasn't been put into direct conversion methods, like TCY (Thermocouple teChnologY. I guess the main problem there isn't the source of heat (SOH), but rather, the source of cold (SOC). :)
Stirling engines and their generators have wearing parts. Which wear out.
I guess the trick with STY (holy cow) is to match the radioactive/heat production decay(RHPD) with the wearing-out time function (WOTF).
